|The MS-7301 tool easily adjusts DzusŪ fastener springs for a perfect fit every time. Great for Warbirds and vintage aircraft. Bend springs in or out with a few simple turns.|
There is no need for the tool profile to mimic the Dzus fastener profile. This weakens the tool in tension. I had two fail on first use. I made a replacement by machining a single hook in a 5/8 AN grade bolt, twice as strong, works great.
Broke the first time I used it. Your better off making your own.
End of tool sheared first time using it.
